MAC address prefix 00:15:16 is registered to URIEL SYSTEMS INC. in the IEEE OUI registry. Any device whose MAC address begins with 00:15:16 has a network interface built by URIEL SYSTEMS INC.. This prefix (the OUI, or Organizationally Unique Identifier) is assigned by the IEEE and is the first three octets of the address — it covers every MAC from 00:15:16:00:00:00 to 00:15:16:FF:FF:FF.

FAQ

Which company owns MAC address prefix 00:15:16?
MAC address prefix 00:15:16 is registered to URIEL SYSTEMS INC. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:15:16 has a network interface built by URIEL SYSTEMS INC..
What is the OUI 00:15:16?
00:15:16 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to URIEL SYSTEMS INC.. It covers every address from 00:15:16:00:00:00 to 00:15:16:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-15-16.
How do I find the manufacturer of a MAC address?
Take the first three octets of the address — in 00:15:16:00:00:00 that is 00:15:16 — and look that prefix up in the IEEE OUI registry. If the second-lowest bit of the first octet is set, the address is locally administered (a randomized or private MAC), which belongs to no manufacturer and will not resolve; modern phones and laptops use these by default on each network.
Where is URIEL SYSTEMS INC. located?
URIEL SYSTEMS INC. is listed at #204 Byucksan Digitalvalley 1st, 212-16, Guro-dong, Guro-gu Seoul KR 152-050 in the IEEE OUI registry entry for 00:15:16. This is the address the organization registered with the IEEE, which may differ from its current operating address.
